How to choose swaddles
Swaddling calms the startle reflex and helps newborns sleep. The key is a snug chest, loose hips, and stopping the moment baby starts to roll.

A square of muslin or cotton you fold. Versatile and breathable; technique-dependent.

Frequently asked
When should I stop swaddling?
At the first signs of rolling — often 8–12 weeks. A swaddled baby who rolls onto their tummy can’t push up safely. Transition to an arms-out swaddle or sleep sack.
Are swaddles safe for sleep?
Yes, when done correctly: baby on their back, snug at the chest, hips loose, and no loose fabric near the face. Always follow safe-sleep guidance.
How tight should a swaddle be?
Firm enough across the chest that it won’t come loose, but you can slip two fingers between the fabric and baby’s chest. Hips must stay loose to protect hip development.
